How to do: Dumbbell Reverse Wrist Curls

Take a seat on the edge of a chair or bench. Hold dumbbells in both hands with your palms facing down. Bend your elbows and rest your forearms on your knees, with your wrists hanging over the ends of your knees. Keeping your palms facing down, curl the dumbbells only using your wrists. Slowly lower the dumbbells back to the starting position. Repeat.
